KlLN-HEAD GUIDE.

SPECIFICATION forming part of Letters Patent No. 270,444, dated.ll'annary 9, 185. 3.

Application filed July 31, 1882. (No model.)

To all whom it may concern:

Be it known that I, GHARLESF. LACOUR,of Grassy Point, in the county ofRockland and State of New York, have invented a new and usefulImprovement in Kiln-Head Guides, of which the following is a full,clear, and exact description.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure l is a front elevation of myimprovement, illustrating its use.Fig. 2 is a sectional elevation ot'the same, taken through the brokenline w 00, Fig. 1.

The object of this invention is to facilitate the setting of the greenbricks in preparing brick-kilns, and also to promote accuracy in formingthe heads of the kilns.

The invention consists in a kiln-head guide constructed with aframehaving a close panel in its lower part and cross-slats in the middle andupper parts, and provided at its upper part with adjustable fasteningsfor connecting it with a. side prop of the kiln. The guide is alsoprovided with cords for giving a true taper to the sides of the centerarch, and with a guide-cord for adjusting it in line with its formerposition, as will be hereinafter fully described.

A represents one of the kiln-shed posts. B are the side props, which areattached to the posts A.

O is the frame of the guide, which is made of a length equal to theheight of the kilnheads, and of a width equal to thethiokness of anarch. The lower part of the guide, for a height equal to the height ofthe fire-chambers ,'is provided with a close panel, D. The part of theguide above the panel D is provided with cross-slats E, attached attheir ends to the side bars of the guide and placed at a distance apartequal to the height oftwo courses of green bricks.

To the top bar of the guide-frame (J, and to a cross-bar at the upperedge of the close panel D, are attached the ends of two cords, F, thelower ends of which are placed at a distance apart equal to thethickness of the lower part of the center arch, and their upper ends areplaced at a distance apart equal to the thickness of the upper part ofthe said center arch. The cords F thus serve as guides in settingthebricks of the center arch, so that the said arch will have a uniforminclination upon-both sides, as shown in Fig. 1. In setting the bricksfor the'other arches the cords F are not used.

' G is a cord which passes through holes in the lower ends of the sidebars of the guideframe 0, and is provided. with pins H at its ends to bedriven into the ground. The cord G may be attached to the posts A, andis intended as a guide in adjusting the lower end of the guide E D E foranother-arch, so that the guide will he in line with its former positionand the headof the kiln will be true.

To the outer sides of the upper parts of the side bars of the.guide-frame G are attached long keepers I, through which and into orthrough the side bars of thefranie C are formed holes to receive thepins J, by which the shanks.

of the hooks K are hinged to the said keepers and side bars. The hooks Kare designed to be hooked upon the upper side prop, B, and are made ofsuch a length as will give the required inclination to the guide 0 DE,and consequently to the head of the kiln, the holesin the keepers Iand in the side bars of the guideframe allowing the hooks K .to beadjusted as the height of the side prop, B, may require.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A kiln-head guide constructed substantially as herein shown anddescribed, and consisting of the frame 0, having a closed panel, D, inits lower part and cross'slats E in its middle and upper part, as setforth.

2. In a kiln-head guide, the combination, with the'guide-frame 0, of thelong 'keepers I and the hinged hooks K, substantially as herein shownand described, whereby the said guide can be readily secured to theupper side prop, as set forth.

3. In a kiln-head guide, the combination, with the frame 0 and thecross-slats E, of the cords F, arranged with their upper ends nearertogether than their lower ends, substantially as herein shown anddescribed, whereby a true guide, when adjusted, can be kept in line withtaper can be given to the center arch, as set its former position andthe head of the kiln forth. kept true, as set forth.

4. In a kiln-head guide, the combination, CHARLES F. LACOUR. 5 with theperforated lower ends of the side bars SVitnesses:

of the frame 0, of the cord G, substantially GEO. W. \VEIANT, J asherein shown and described, whereby the A. BICKELMANN.
